+# Lucene.NET 4.8.0-beta00016 Release Notes
+
+---
+
+> This release contains several important bug fixes and performance
enhancements.
+
+## Breaking Index Changes
+
+There are 2 breaking changes that may affect some users when reading indexes
that were created from version 4.8.0-beta00015 and all prior 4.8.0 beta
versions (not including 3.0.3).
+1. A bug was fixed in the generation of segment file names. This only affects
users with more than 10 segments in their index.
+2. `Lucene.Net.Documents.DateTools` has been modified to return _milliseconds
since Unix epoch_ (that is, since Jan 1, 1970 at 00:00:00 UTC) by *default* to
match Java Lucene. This only affects users who explicitly use
`Lucene.Net.Documents.DateTools` in their application and store the result (in
.NET ticks) in their index.
+
+If you are affected by either of the above issues, it is recommended to
regenerate your indexes during upgrading. However, if that is not feasible, we
have provided the following workarounds.
+
+1. If you have a large index with more than 10 segments, see
[#576](https://github.com/apache/lucenenet/pull/576) for details on how to
enable legacy segment name support.
+2. If you are storing the result of
`Lucene.Net.Documents.DateTools.StringToTime(string)` or
`Lucene.Net.Documents.DateTools.Round(long)` (a `long`) in your index, you are
storing .NET ticks. There are now optional parameters `inputRepresentation` and
`outputRepresentation` on these methods to specify whether the `long` value
represents .NET ticks, .NET ticks as milliseconds, or millisenonds since the
Unix epoch. To exactly match version 4.8.0-beta00015 and prior (including prior
major v [...]
+ - `Lucene.Net.Documents.DateTools.StringToTime(string,
NumericRepresentation)` should specify `NumericRepresentation.TICKS` for
`outputRepresentation`.
+ - `Lucene.Net.Documents.DateTools.Round(long, NumericRepresentation,
NumericRepresentation)` should specify
`NumericRepresentation.TICKS_AS_MILLISECONDS` for `inputRepresentation` and
`NumericRepresentation.TICKS` for `outputRepresentation`.
+
+## .NET Framework Recommendations
+
+It is recommended that all .NET Framework users migrate as soon as possible.
+
+1. In cases where `Lucene.Net.Support.WeakDictionary<TKey, TValue>` was used
in .NET Framework and .NET Standard 2.0 due to missing APIs, but there is now a
better solution using `Prism.Core`'s weak events in combination with
`ConditionalWeakTable<TKey, TValue>`, which means memory management is handled
entirely by the GC in `Lucene.Net.Index.IndexReader`,
`Lucene.Net.Search.FieldCacheImpl`, `Lucene.Net.Search.CachingWrappingFilter`
and `Lucene.Net.Facet.Taxonomy.CachedOrdinalsReader`. S [...]
+2. All known issues with loss of floating-point precision on .NET Framework
x86 have been fixed.
+
+## Change Log
+
+### Breaking Changes
+* [#547](https://github.com/apache/lucenenet/pull/547) -
`Lucene.Net.Util.StringHelper.GOOD_FAST_HASH_SEED`: converted from a static
field to a property and marked obsolete. Added a new property
`GoodFastHashSeed`. Removed `SystemProperties` call to populate the value of
the field, since NUnit only allows us to generate a seed per test, and we need
a way to inject the seed value for repeatability.
+* [#547](https://github.com/apache/lucenenet/pull/547) -
`Lucene.Net.TestFramework`: Added `LuceneSetUpFixtureBuilder` class to load
either a subclass or our default instance of `LuceneTestFrameworkInitializer`.
Also added `LuceneTestCase.SetUpFixture` to control initialization of
`LuceneTestFrameworkInitializer` so it is only called on setup and teardown for
the assembly. Added `Initialize()` method to `LuceneTestFrameworkInitializer`
that *must be used* when setting factories during testing.
+* [#547](https://github.com/apache/lucenenet/pull/547) -
`Lucene.Net.TestFramework.Util.LuceneTestCase`: Deprecated `GetClassType()`
method and added `TestType` property
+* [#547](https://github.com/apache/lucenenet/pull/547) -
`Lucene.Net.TestFramework.Util.AbstractBeforeAfterRule``: Removed
`LuceneTestCase` parameter from `Before()` and `After()` methods.
+* [#551](https://github.com/apache/lucenenet/pull/551) - Changed constructors
of `Lucene.Net.Util.NumberFormat` and
`Lucene.Net.QueryParsers.Flexible.Standard.Config.NumberDateFormat` to accept
`IFormatProvider` rather than `CultureInfo` and changed
`Lucene.Net.Util.NumberFormat.Culture` property to
`Lucene.Net.Util.NumberFormat.FormatProvider`.
+* [#554](https://github.com/apache/lucenenet/pull/554) - `Lucene.Net.Misc`:
Made `DocFreqComparer` and `TotalTermFreqComparer` into static singletons, only
accessible by the `Default` property.
+* [#428](https://github.com/apache/lucenenet/pull/428),
[#429](https://github.com/apache/lucenenet/pull/429),
[#570](https://github.com/apache/lucenenet/pull/570) -
`Lucene.Net.Search.FieldComparer`: Redesigned implementation to use reference
types for numerics (from J2N) to avoid boxing.
+* [#570](https://github.com/apache/lucenenet/pull/570) -
`Lucene.Net.Search.FieldCache.IParser`: Renamed method from `TermsEnum()` to
`GetTermsEnum()` to match other APIs
+* [#570](https://github.com/apache/lucenenet/pull/570) - `Lucene.Net.Queries`:
`ObjectVal()` returns a `J2N.Numerics.Number`-derived type rather than a value
type cast to object. Direct casts to `int`, `long`, `double`, `single`, etc.
will no longer work without first casting to the `J2N.Numerics.Number`-derived
type. Alternatively, use the corresponding `Convert.ToXXX()` method for the
type you wish to retrieve from the object.
+* [#574](https://github.com/apache/lucenenet/pull/574) -
`Lucene.Net.Suggest.Fst.FSTCompletionLookup/WFSTCompletionLookup`: Changed
`Get()` to return `long?` instead of `object` to eliminate boxing/unboxing
+* [#574](https://github.com/apache/lucenenet/pull/574) -
`Lucene.Net.Index.MergePolicy::FindForcedMerges()`: Removed unnecessary
nullable from `FindForcedMerges()` and all `MergePolicy` subclasses
+* [#574](https://github.com/apache/lucenenet/pull/574) -
`Lucene.Net.Replicator`: Changed callback signature from `Func<bool?>` to
`Action`, since the return value had no semantic meaning
+* [#575](https://github.com/apache/lucenenet/pull/575) -
`Lucene.Net.Index.DocValuesFieldUpdates`: Refactored so the subclasses will
handle getting the values from `DocValuesFieldUpdatesIterator` or
`DocValuesUpdate` via a cast rather than boxing the value. Also marked internal
(as well as all members of `BufferedUpdates`), since this was not supposed to
be part of the public API.
+* [#573](https://github.com/apache/lucenenet/pull/573),
[#576](https://github.com/apache/lucenenet/pull/576) - Changed segment file
names to match Lucene 4.8.0 and Lucene.NET 3.x
+* [#577](https://github.com/apache/lucenenet/pull/577) -
`Lucene.Net.Index.SegmentInfos`: Changed `Info()` method to an indexer (.NET
Convention)
+* [#580](https://github.com/apache/lucenenet/pull/580) -
`Lucene.Net.Documents.DateTools` - Added `NumericRepresentation` enum to allow
converting to/from long in the following formats:
+ - Unix Epoch (default): Milliseconds since Jan 1, 1970 12:00:00 AM UTC.
+ - Ticks: The raw ticks from `DateTime` or `DateTimeOffset`.
+ - Ticks as Milliseconds: This is for compatibility with prior versions of
Lucene.NET (3.0.3 and 4.8.0-beta00001 - 4.8.0-beta00015). The conversion done
on input values is `time * TimeSpan.TicksPerMillisecond` and the conversion to
output values is `time / TimeSpan.TicksPerMillisecond`.
+
+ **The `long` return value from
`Lucene.Net.Documents.DateTools.StringToTime(string, NumericRepresentation)`
has been changed from `NumericRepresentation.TICKS` to
`NumericRepresentation.UNIX_TIME_MILLISECONDS` by default.**
+
+ **The `long` input parameter provided to
`Lucene.Net.Documents.DateTools.Round(long, NumericRepresentation,
NumericRepresentation)` has been changed from
`NumericRepresentation.TICKS_AS_MILLISECONDS` to
`NumericRepresentation.UNIX_TIME_MILLISECONDS` by default.**
+
+ **The `long` return value from `Lucene.Net.Documents.DateTools.Round(long,
NumericRepresentation, NumericRepresentation)` has changed from
`NumericRepresentation.TICKS` to `NumericRepresentation.UNIX_TIME_MILLISECONDS`
by default.**
+* [#580](https://github.com/apache/lucenenet/pull/580) -
`Lucene.Net.Documents.DateTools` - De-nested `Resolution` enum and renamed
`DateResolution`.
+* [#580](https://github.com/apache/lucenenet/pull/580) -
`Lucene.Net.QueryParsers.Flexible.Standard`: Changed numeric nodes to accept
and return `J2N.Numerics.Number`-derived types instead of `object`.
+* [#581](https://github.com/apache/lucenenet/pull/581) - **SWEEP:**
`Lucene.Net.Util.Fst`: Changed API to use `J2N.Numerics.Int64` instead of
`long?` for generic closing type as it was designed to use reference equality
comparison.
+* [#581](https://github.com/apache/lucenenet/pull/581) - **SWEEP:**
`Lucene.Net.Util.Fst`: Added class constraints to each generic FST type and
reverted to reference equality comparisons.
+* [#581](https://github.com/apache/lucenenet/pull/581),
[#279](https://github.com/apache/lucenenet/pull/279) -
`Lucene.Net.Util.Fst.Int32sRefFSTEnum`: Added `MoveNext()` method and marked
`Next()` method obsolete. This change had already been done to BytesRefFSTEnum,
which made them inconsistent.
+* [#583](https://github.com/apache/lucenenet/pull/583) -
`Lucene.Net.QueryParsers.Flexible`: Removed unnecessary nullable value types
from `ConfigurationKeys` and configuration setters/getters in
`StandardQueryParser`. Added `AbstractQueryConfig.TryGetValue()` method to
allow retrieving value types so they can be defaulted properly.
+* [#583](https://github.com/apache/lucenenet/pull/583) -
`Lucene.Net.Queries.Function.ValueSources.EnumFieldSource::ctor()` - changed
`enumIntToStringMap` to accept `IDictionary<int, string>` instead of
`IDictionary<int?, string>` (removed unnecessary nullable)
+* [#587](https://github.com/apache/lucenenet/pull/587) -
`Lucene.Net.TestFramework.Store.MockDirectoryWrapper`: Renamed
`AssertNoUnreferencedFilesOnClose` to `AssertNoUnreferencedFilesOnDispose`
+* [#619](https://github.com/apache/lucenenet/pull/619) - `Lucene.Net.Spatial`:
Upgraded to new Spatial4n NuGet package that unifies the types from
Spatial4n.Core and Spatial4n.Core.NTS
+* [#619](https://github.com/apache/lucenenet/pull/619) -
`Lucene.Net.Spatial.Prefix.Tree.Cell`: Renamed `m_outerInstance` >
`m_spatialPrefixTree` and constructor parameter `outerInstance` >
`spatialPrefixTree`
+* [#619](https://github.com/apache/lucenenet/pull/619) -
`Lucene.Net.Spatial.Prefix.AbstractPrefixTreeFilter.BaseTermsEnumTransverser`:
renamed `m_outerInstance` > `m_filter`, constructor parameter `outerInstance` >
`filter`
+* [#619](https://github.com/apache/lucenenet/pull/619) -
`Lucene.Net.Spatial.Prefix.AbstractPrefixTreeFilter`: De-nested
`BaseTermsEnumTraverser`class
+* [#619](https://github.com/apache/lucenenet/pull/619) -
`Lucene.Net.Spatial.Prefix.Tree.GeohashPrefixTree.Factory`: de-nested and
renamed `GeohashPrefixTreeFactory`
+* [#619](https://github.com/apache/lucenenet/pull/619) -
`Lucene.Net.Spatial.Prefix.Tree.QuadPrefixTree.Factory`: de-nested and renamed
`QuadPrefixTreeFactory`
+* [#619](https://github.com/apache/lucenenet/pull/619) -
`Lucene.Net.Spatial.Prefix.AbstractVisitingPrefixTreeFilter`: De-nested
`VisitorTemplate` class and changed protected field `m_prefixGridScanLevel` to
a public property named `PrefixGridScanLevel`.
+* [#619](https://github.com/apache/lucenenet/pull/619) -
`Lucene.Net.Spatial.Query`: Renamed `UnsupportedSpatialOperation` >
`UnsupportedSpatialOperationException` to match .NET conventions
+
+### Bugs
+* [#363](https://github.com/apache/lucenenet/pull/363),
[#534](https://github.com/apache/lucenenet/pull/534) -
`Lucene.Net.Replicator.Http.HttpReplicatorTest::TestBasic()`. This was failing
intermittently due to the Timeout value being set to 1 second instead of the 60
second value that was used in Java. It has been increased to the .NET default
of 100 seconds.
+* [#363](https://github.com/apache/lucenenet/pull/363),
[#534](https://github.com/apache/lucenenet/pull/534) -
`Lucene.Net.Replicator.IndexAndTaxonomyReplicationClientTest::TestConsistencyOnExceptions()`
and
`Lucene.Net.Replicator.IndexReplicationClientTest::TestConsistencyOnExceptions()`
were failing due to to exceptions being raised on the worker thread and
missing locks, which have both been addressed.
+* [#535](https://github.com/apache/lucenenet/pull/535) - Added
`[SuppressCodecs]` attribute where required for custom Lucene.NET tests
+* [#536](https://github.com/apache/lucenenet/pull/536) - Modified all
`TermsEnum.MoveNext()` methods to return a check for `null` rather than

`Lucene.Net.TestFramework.Index.BasePostingsFormatTestCase`: Removed
`IndexOptions.NONE` from the list of available options, since it is not a valid
test option
+* [#539](https://github.com/apache/lucenenet/pull/539) -
`Lucene.Net.Grouping.Term.TermAllGroupHeadsCollector`: Use
`NumericUtils.SingleToSortableInt32()` to compare floating point numbers (Fixes
`AllGroupHeadCollectorTest.TestRandom()` on .NET Framework x86).
+* [#540](https://github.com/apache/lucenenet/pull/540) -

(from 4.9.0).
+* [#545](https://github.com/apache/lucenenet/pull/545),
[#565](https://github.com/apache/lucenenet/pull/565) -
`Lucene.Net.Index.TestDuelingCodecs::TestEquals()`: There was a missing ! in

+* [#606](https://github.com/apache/lucenenet/pull/606) -
`Lucene.Net.Search.FieldCacheImpl.Cache<TKey, TValue>::Put()`: Logic was
inverted on `innerCache` field so the value was being updated if exists, when
it should not be updated in this case
+* [#606](https://github.com/apache/lucenenet/pull/606) -
`Lucene.Net.Search.FieldCacheImpl::Cache<TKey, TValue> (Put + Get)`: Fixed
issue with `InitReader()` being called prior to adding the item to the cache
when it should be called after
+* [#619](https://github.com/apache/lucenenet/pull/619) -
`Lucene.Net.Spatial.Query.SpatialArgs::ctor()`: Set `operation` and `shape`
fields rather than calling the virtual properties to set them (which can cause
initialization issues for subclasses)
+
+### Improvements
+* [#538](https://github.com/apache/lucenenet/pull/538) -
`Lucene.Net.TestFramework.Search.CheckHits::CheckHitCollector()`: Removed
unnecessary call to `Convert.ToInt32()` and simplified collection

[#567](https://github.com/apache/lucenenet/pull/567) - Removed `[Serializable]`
support for all classes except for the following (See
[#567](https://github.com/apache/lucenenet/pull/567) for a complete list)
+ * Exceptions
+ * Collections
+ * Low-level holder types (such as BytesRef, CharsRef, etc.)
+ * Stateless `IComparer<T>` implementations that are publicly exposed
directly or through collections
+* [#568](https://github.com/apache/lucenenet/pull/568) -
`Lucene.Net.TestFramework.Util.LuceneTestCase::NewSearcher()`: Added missing
event handler to shut down `LimitedConcurrencyLevelTaskScheduler` to prevent it
from accepting new work when we are attempting to end the background process.
+* [#568](https://github.com/apache/lucenenet/pull/568) - `Lucene.Net.Support`:
Factored out `ICallable<V>` and `ICompletionService<V>` interfaces, as they are
not needed
+* [#570](https://github.com/apache/lucenenet/pull/570) - **PERFORMANCE:**
`Lucene.Net.Search.NumericRangeQuery`: Eliminated boxing when converting from T
to the numeric type and when comparing equality

`Lucene.Net.QueryParsers` - Added support for `TimeZoneInfo` when converting
to/from string (Classic and Flexible query parsers)
+* [#580](https://github.com/apache/lucenenet/pull/580) -
`Lucene.Net.QueryParsers.Classic.QueryParserBase`: Use `TryParse()` instead of

`Lucene.Net.TestFramework`: Fixed random seed functionality so it is
repeatable, so random tests can be more easily debugged. The random seed and
how to configure a test assembly to repeat the same result is appended to the
output message of the test (which becomes visible upon failure). The
